✔ 最佳答案
z + z + z = 900

2z+z=900

3z=900

z=300

z=300 300+300+300=900 將900÷3就得所以z=300

z + z + z = 900
3z = 900
z=300

似乎好無聊……

z+z+z=900
3z=900
z=300

一題可以一秒內想到答案的問題。

驗算:
300+300+300
=300x3
=900

z + z + z = 900
3z=900
z=300
2006-12-22 11:07 pm
z+z+z=900
3z=900
3z/3=900/3
z=300
2006-12-22 10:54 pm
z+z+z=900
3z=900
3z/3=900/3
z=300

***3z/3同300/3(自己用''份''線黎做,因為冇人會用''/'')***

z + z + z = 900
3Z = 900
Z = 300

z + z + z = 900
3z = 900
z = 900/3
z=300
